Application filed October 5, 1906, Serial No. 337,575. Renewed June 16, 1916. Serial No. 104,120.

To all whom it may concern:

Be it known that I, EDGAR F. HATHAWAY, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an lniprovement in ire-Coiling Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to wire coiling machines, the product whereof may be used for a large variety of purposes, but is particularly intended for use as a normally contracted extensible member employed in connection with the harnesses of looms to engage the heddles thereof individually and regularly space them and in cooperation with other elements of a warp drawing-in machine to assist in spreading the heddle eyes to facilitate the drawing-in operation.

In the accompanying drawings, wherein merely one type or embodiment of the invention is illustrated, in order that the prin ciples of operation thereof may be made clear, Figure 1 represents a side elevation of one form of wire coiling apparatus embodying my invention, many of the herein shown horizontally disposed parts being broken away mid length for convenience of illustration; Fig. 2 is an end elevation of the mechanism shown in Fig. 1, looking from the left in said figure; Fig. 3 is a longitudinal vertical section of one form of carriage mounted for relatively axial movement with respect to the mandrel whereon the wire is coiled; Fig. 4 is an end elevation of the said carriage looking from the right in Fig. 3; Fig, 5 is a rear elevation of the said carriage, showing the point at which the wire is delivered thereto; Fig. 6 is an enlarged longitudinal sectional view of the abutment and abutment cooperative member, which, in the present type of the invention, co-act with the mandrel in the coiling of the wire, the curvature of the adjacent ends which I sometimes resort to, being greatly exaggerated for purposes of description and illustration; Fig. 7 is an enlarged detail in side elevation of a portion of the left-hand end of the machine shown in Fig. 1, viewing said figure; Fig. 8 is an end elevation of a form of clutch herein employed for imparting rotation to the mandrel; Fig. 9 is a detail in plan showing a portion of a terminal supporting bar having an adjustable contact member thereon, whereby the machine is suitably stopped; Fig. 10 represents in end and side elevation the adjustable contact member of the terminal supporting bar; Fig. 11 represents a form of clutch preferably employed to prevent opposite rotation of the mandrel when the bar is thrown off the machine; and, Fig. 12 illustrates diagrammatically a system of wiring employed to electrically control the stopping of the machine.

Having now reference to that single type or embodiment of the invention herein chosen for illustration and referring more particularly to Figs. 1 and 2, the operative parts of the machine are supported upon end uprights or standards, 1, 1, having suitably disposed thereon at proper distances apart horizontal bearings, 2, wherein are suitably supported horizontal connecting bars or rods, 3. Supported for rotation in suitable bearings, 4, 4, in said uprights, 1, 1, are arranged one or any desired number. of rotatable mandrels, 5, two being herein shown. It is apparent that the mandrels need not be arranged in a vertical series, as shown, but that their arrangement may be largely varied, as desired. If desired, one end of said mandrel or mandrels, and as herein shown the right-hand end (Fig. 1) may be received within enlarged bearings, 4, provided with removable bearing nuts, 6, whereby the mandrels may be steadied in their rotative movement, which may be imparted to them in any desired manner. Herein I have shown each of them as provided with clutch members, 7 splined thereon and supported for longitudinal movement with respect to the opposing and preferably band driven clutch members, 8, through the medium of a clutch operating carriage composed of vertical end bars, 9 and 10, the latter preferably having segmental bearings frictionally impinging against the adjacent, horizontal rods, 3, for sliding movement thereon, said bars, 9 and 10, being herein shown as connected by horizontally arranged rods, 11. Any suitable form of clutch may be employed, but herein I have shown in Figs. 7 and 8, a preferred or convenient type provided with relatively movable interengaging conical members "sleeve, 14, mounted for sliding movement clutch of any preferred construction.

.In the present type of the invention the wire to be coiled is delivered to the mandrel and one end thereof is attached thereto, so that in the rotation of the mandrel the wire is coiled thereon and preferably against a suitable abutment disposed in wire coiling relation to said mandrel and adapted for relative axial movement with respect thereto, in'order that the wire may be progressively coiled. In the present type of the invention axial movement is imparted to the so-called abutment, herein shown (Figs. 3 and 6) as a upon the mandrel and preferably clamped in a suitable carriage, 15, which, during the coiling of the wire, is in this type of the invention fed or moved axially of the corre- 'sponding mandrel by the wire as coiled, such 7 method, of carriage movement being in. this instance preferred. to a carriage feeding means, which might, howev er, be employed in certa n cases where desired. It is apparent' that the relative axial movement of the oarriage and mandrel mayin suitable cases V besecured by axial movement'of the latter.

The carriage herein shown is preferably positioned between adjacent horizontal .bars,

. 3, and to that end is'shown as provided with segmental or, if preferred, encircling bearingsat the top and bottom thereof, which preferably so closely engage the said bars as to secure suflicient friction to oppose the feeding movement imparted by'the coiling Wire- I f no carriage feeding means beemployed '7 and "the coiling" of the wire'itselfbe relied upon to move thecarriage' axially of its man- .d.rel, and if said carriage providedwith frictional or other means to; opposethe car ri'age onward forcing movement of the coiling wire, supplemental means may beprov ded to. oppose 511Gb. onward movement and i 'as fa convenient type thereof, there are herein shown (F1g.-1) 'weights, 16, which "maybe varied as desired, and'are suitably connected Lby bands or other flexible mem- 13 3-.., 11-7, herein shown as guided over loose pulleys, 18,1nounted upon a bracl;et, 19, said 7 beingadapted to be connected to the respectivecarriages,but 'hereinshown as de- Ztached therefrom.

c5 '1: i lnfthe-" presenttype ofthe invention wire for each carriage is carried (Fig. 9) upon spools, 19, suitably mounted in upright standards, 20, preferablyv at the rear of the carriages, and is delivered to the carriages in any suitable manner, but as herein shown (Fig. 5) through an opening, 21, suitably provided in a preferably detachable plate, 22, the wire then passing to the corresponding mandrel, 5, to which one end thereof is preferably attached, so that in the rotation of the mandrel the wire is wound thereabout in a coil or helix the spires or turns of which are preferably in contact with each other, but may be more or less separated, according to the rate of relative axial movement of the carriage, which may be varied as desired by opposing less friction to the said relative movement of the carriage or in any other preferred manner.

' Viewing Fig. 3, it will be apparent that the wire, as delivered to the rotating mandrel, is, in' the present embodiment of the invention, coiled thereabout and against the end of the abutment, 14, which, being herein shown as mounted upon the carriage, 15, is, by the coiling of the wire, gradually moved axially of the mandrel, each newly positioned spire or turn of the helix or coil be ing laid between the end, 23, of the abutment, 14, and the forward end of the coil.

' In the present type of the invention I prefer 'to'employ in conjunction with the abutment, 14, a so-called abutment cooperative member, 24, herein shown as disposed coaxially with the abutment, 14, and adjacent the same, so that the wire is delivered to the mandrel between the said abutment and abutment cooperative member. It will be observed (Fig. 3) that herein said abutment cooperative member is shown as having an axial opening of a diameter exceeding that of the abutment, 14, and preferably by the diameter of the wire or the enlarged dimension. of the wire in cross section, if a wire having an enlarged dimension in cross sec tion be employed, whereby in the onward movement of the carriage the said abutment cooperative member moves over the coiled wire, which, at the beginning of the operation, is preferably threaded through the axial opening in the abutment coiiperativu member to the point where it is fastened to the mandrel.

Then an abutment cooperative member is employed the same may be fixedly positioned with regard to the abutment; but inasmuch as any given quantity of wire is apt to vary somewhat in diameter throughout its extent, I preferably mount the abutment cooperative member with capacity for axial yieldingmovement, although it is apparent that such movement being relative Although said yielding movement may be secured in many different ways, I have herein shown the said abutment cooperative member, 24, as having such capacity and to that end (Fig. 3) have mounted the same for sliding movement in a boss, 25, of the carriage and provided limiting means to oppose its movement in a direction away from the abutment, 14, such means herein comprising a vertically disposed plate, 26, having an open ended slot, 27, therein, through which the mandrel passes, said slot being of less diameter than the outer dimension of the abutment cooperative member, 24, thereby presenting a stop to the axial yielding movement of the latter. I preferably so mount the plate, 26, that the position thereof may be adjusted axially of the mandrel and for that purpose have in this type of the invention, provided a horizontal headed pin, 28, suitably mounted in an axial opening, 29, in the carriage and preferably guided therein by the reduced end of 'a screw, 30, engaging an elongated socket in said pin, the opposite end whereof being herein shown as having a nut, 31, threaded thereon, between which and a shoulder of the carriage is provided a coil spring, 32, the tension of which may be adjusted by the nut, 31. The said spring tends normally to force to the left, viewing Fig. 3, the plate, 26, which is herein shown as having a slot, 33, near the upper end thereof for the passage of said pin, the said plate being thus yieldingly positioned between the headed end of the pin and the carriage, and pivotally mounted at its opposite end upon a pin, 34, axially disposed with respect to the mandrel and preferably having a screw threaded adjustment, 35, in the carriage, whereby the plate may be vertically alined, a coil spring, 36, being herein shown as encircling said pin between the plate, 26, and a shoulder formed in the carriage, the member 24 thus being removable without disturbing the adjustment of the coiled spring 32.

It is apparent that wire of any chosen diameter and any desired cross section may be coiled in the manner previously described, but I sometimes prefer to employ a wire having an enlarged dimension in cross section and sometimes to dispose such enlarged cross section at right angles to the axis of the coil or the mandrel. In such cases the wire may be delivered as desired and irrespective of the disposition of the enlarged cross dimension or section thereof to-the opening, 21, and is received between the adjacent ends of the abutment, l4, and abutment cooperative member, 24, in cases where the latter is employed, by which the wire, however received thereby, may be so positioned and if necessary, partially turned or rotated, that the enlarged dimension thereof in cross section is disposed as deslcribed at right angles to the axis of the 001 I have discovered that the spires or turns of the coil or helix have a. tendency as coiled, to assume a position in which the opposing faces of the spires are not truly normal to the axis of the coil, but slightly inclined thereto in one direction or the other. To counteract this tendency I may and preferably do employ what I herein term a spire truing device. To that end, in the present type of the invention I preferably slightly concave the wire receiving end of the abut ment, 14, this construction being shown very much exaggerated in Figs. 3 and 6 for purposes of illustration. I prefer to render the adjacent end of the abutment cooperative member, 24, correspondingly convex, if such member be employed, and have herein shown the same to an exaggerated degree.

The face of the abutment is substantially normal to the axis of the mandrel, although, as described, I preferably provide spire truing means effected, in this embodiment of my invention, by rendering ,the adjacent ends of the abutment and abutment cooperative member respectively concave and convex and preferably very slightly so.

According to the disclosed embodiment of the invention, I provide an abutment cooperative member, the faces whereof are curved with respect to a plane cutting the mandrel at right angles to the axis of said mandrel. Said faces may furthermore be defined as eccentric to said cuttingplane, and also as deflected preferably slightly from parallelism with the spires of the completed wire.

I prefer to employ means for automatically stopping each mandrel upon the completion of the coil formed thereon and preferably employ means whereby the rotation of each mandrel may be stopped independently of that of the others, if a plurality be used. As illustrating one embodiment of means for accomplishing this result, I have herein provided (Figs. 1, 9 and 12) one or more horizontally disposed terminal supporting bars, 37, preferably mounted in the end standards, 1, and suitably insulated therefrom, the number of terminal supporting bars employed corresponding to the number of mandrels and each bar having preferably mounted thereon for longitudinal adjustment (Fig. 10) a terminal or contact member, 38, herein shown as consisting of a sleeve, 39, having a set screw, 40, to secure the same in its adjusted position and a detachable contact plate, 41, forming (Fig. 12) a terminal of an electric circuit, the other terminal thereof being furnished by the carriage and preferably (Fig. 4) by a pin or wire, 42, laterally extending therefrom to 7 portion of the clutch opera-ting, carriage,
